The trend in 7-day daily average number of persons tested provides an indication of the direction of COVID-19 testing in Los Angeles County. Conducting more tests can result in more confirmed cases of COVID-19 and supports efforts to control local spread of the virus.

Testing Positivity Rate

7-Day Daily Average:
What This Means

The Testing Positivity Rate is defined as the percentage of tests reported that are positive. The 7-Day Daily Average Testing Positivity Rate provides a more current picture of how many people tested positive, as opposed to the cumulative Testing Positivity Rate, which would date back to the beginning of the pandemic. We use a rolling 7-day average to smooth some of the fluctuations we see in the daily numbers due to reporting and processing lags that are a part of reportable disease surveillance.

Total Deaths Reported*:

*including deaths reported by Long Beach and Pasadena Health Departments
What This Means

Using the 7-Day Daily Average from Deaths 7 Days Ago prevents us from putting too much weight in a single daily number and it accounts for daily fluctuations in deaths reported to the health department and shows a clearer picture of death trends.

by Race, Ethnicity and Poverty Level

What This Means

COVID-19 has exposed numerous inequities in our system, where low-income residents and people of color have higher risk of death from COVID-19 than whites and areas of low poverty. The Death Rate is the number of deaths from COVID-19 per 100,000 population in each race/ethnicity group. We can see that Latino/Latinx and African Americans are experiencing a disproportionate rate of deaths from COVID-19.

We also characterize deaths by calculating area-based measures of socioeconomic positions to identify areas with varied levels of economic resources so we can track how they are impacted. In LA County, our current death rate in people living in the lowest resource areas is approximately 4 times higher than people living in the highest-resourced areas. This measure, also referred to as “area poverty” reflects the percentage of households living at or below the federal poverty line. Area poverty estimates are derived from the US Census 5-year (2013-2017) American Community Survey at the census tract level.
